Example of ASCII Code Designation
If “OMRON” is written to the five bytes beginning with address 10h in the
memory, the addresses will be occupied with the following data.
“O”
“M”
“R”
“O”
“N”
ID Tag memory
Address
Two characters of data are treated as two-digit hexadecimal data, so only two-
digit hexadecimal values 00 through FF can be accepted. The two hexadecimal
characters occupy one byte of ID Tag memory.
Example of HEX Code Designation
If “1234” is written to the two bytes beginning with address 20h, the addresses
will be occupied with the following data.

dress and bytes. A command error will result if a value not within the range is
specified.
